It to avoid passing through the unfavorable geologic bodies such as landslide talus completely to be difficult to realize, if high-speed railway passes through cunning in the form of heavy cut
Slopes, then reinforcing landslide-mass, high-speed railway Deformation control become the technical problem that must be solved, especially non-fragment orbit high-speed iron
Road, deformation are controlled with grade, therefore propose that a kind of suitable landslide heavy cut ballastless track roadbed structure has important meaning
Justice, and should have the characteristics that economical, safe and environment-friendly.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of landslide heavy cut ballastless track roadbed structures, to have
Effect solves the problems, such as the stringent settlement control of non-fragment orbit in the reinforcing of slip mass heavy cut and slip mass.
It is as follows that the utility model solves technical solution used by its technical problem:
A kind of landslide heavy cut ballastless track roadbed structure of the utility model, it is characterized in that including: to be reinforced on the inside of cutting
Friction pile is reinforced on the outside of friction pile and cutting, the upper side of heavy cut, lower side is arranged in corresponding longitudinal gap, and its underpart passes through
Sliding surface enters stable rock-soil layer, lays compacted soil between reinforcing pile and on the outside of adjacent two cutting between reinforcing pile on the inside of adjacent cutting
Nail；Top cross-bar, one end and outside reinforce at the top of friction pile and consolidate, and the other end reinforces friction pile consolidation with corresponding inside；Bottom
Portion's crossbeam, is arranged at the top of the ground of heavy cut, and friction pile is reinforced with corresponding inside respectively for both ends and outside reinforces antiskid
Stake consolidation；Loading plate and track structure, loading plate are arranged at the top of adjacent base cross members, and track structure is fixed at carrying
On plate top surface.
The utility model has the beneficial effects that inside reinforces friction pile, outside reinforces friction pile and top cross-bar and bottom
Crossbeam is fixedly connected to form integral frame structure, solves big drag anti-sliding support demand caused by heavy cut in slip mass；Top
The setting of portion's crossbeam effectively improves inside and reinforces friction pile and outside reinforcing friction pile stress form and control structure not

Detailed description of the invention
This specification includes such as next width attached drawing:
Fig. 1 is a kind of section diagram for the heavy cut ballastless track roadbed structure that comes down of the utility model；
Component and corresponding label are shown in figure: inside reinforces friction pile 1, outside reinforces friction pile 2, top cross-bar 3, bottom
Portion's crossbeam 4, loading plate 5, track structure 6, soil nail wall 7, slip mass A.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples.
Referring to Fig.1, a kind of landslide heavy cut ballastless track roadbed structure of the utility model, it is characterized in that including: in cutting
Side reinforces and reinforces friction pile 2 on the outside of friction pile 1 and cutting, and the upper side of heavy cut, lower side is arranged in corresponding longitudinal gap,
Lower part passes through sliding surface and enters stable rock-soil layer, reinforces between friction pile 1 and reinforces on the outside of adjacent two cutting anti-on the inside of adjacent cutting
It is laid between sliding pile 2 and reinforces soil nailing 7；Top cross-bar 3, one end and outside reinforce at the top of friction pile 2 and consolidate, the other end with it is corresponding
Inside reinforces friction pile 1 and consolidates；Base cross members 4, are arranged at the top of the ground of heavy cut, and both ends add with corresponding inside respectively
Gu friction pile 1 and outside reinforce friction pile 2 and consolidate；Adjacent base cross members are arranged in loading plate 5 and track structure 6, loading plate 5
4 tops, track structure 6 are fixed on 5 top surface of loading plate.
Referring to Fig.1, the inside reinforces friction pile 1, outside reinforces friction pile 2 and top cross-bar 3 and base cross members 4 are fixed
Connection forms integral frame structure, can resist very big external force, big caused by heavy cut so as to solve in slip mass
Drag anti-sliding support demand.Inside reinforces friction pile 1 and reinforces connecting by the consolidation of beam for friction pile 2 with outside, by slip mass
The unfavorable soil pressure of lower side is converted into advantageous landslide resistance.The setting of top cross-bar 3, which effectively improves inside and reinforces, to be resisted
Sliding pile 1 and outside reinforce 2 stress form of friction pile and control the disadvantageous deformation of structure.The setting of base cross members 4 enhances group
